Providing Safe, Reliable and Efficient Natural Gas Service for over 100 Years!

The City of Mesa has been offering safe, reliable, and efficient natural gas utility service for over 100 years. Established in 1917, our natural gas service area now includes roughly 107 square-miles in Mesa, as well as 227 square-miles in Pinal County, where in total we serve more than 65,000 customers. The area in Pinal County is known as the Mesa Magma Certified Area.

Performance Measures
Gas O&M Cost Per Customer
O&M Cost/Customer is a good indicator of whether the costs of our gas staff and operations are growing proportionally in comparison to the growth of the gas system as measured by the change in customers.
Energy Resources uses O&M Cost/Customer as a measure of Performance Improvement by comparing actual O&M Cost/Customer in the current year to the budgeted O&M dollars from the prior year divided by the forecasted customer count (our target values). The data also allows a comparison of how actual O&M Cost/Customer changes from year to year and allows us to measure whether our costs are increasing in proportion to the growth in the number of customers we serve.
Thus, O&M Cost/Customer is a measure of “technical” efficiency where O&M Costs would be the “input” and Customers, when served safely and reliably, would be the measure of output. Efficiency measures how well a business converts inputs such as capital, labor & materials into outputs such as revenue, products and services.
